[issue1140] re.sub returns str when processing empty unicode string
|
|
New submission from Beda Kosata:
While re.sub normally returns unicode strings when processing unicode,
it returns a normal string when dealing with an empty unicode string.
Example:
>>> print type( re.sub( "XX", "", u""))
<type 'str'>
>>> print type( re.sub( "XX", "", u"A"))
<type 'unicode'>
This inconsistency could lead to annoying bugs (at least it did for me :)
